INSTALLATION
PROCEDURE
1. INSTALL SPIRAL CABLE SUB-ASSEMBLY WITH SENSOR
(a) Check that the ignition switch is OFF. |
|
(b) Check that the battery negative (-) terminal is disconnected.
CAUTION:
Wait at least 90 seconds after disconnecting the cable from the negative (-) battery terminal to prevent airbag and seat belt pretensioner activation.
(c) Confirm that the front tires face straight forward.
(d) Engage the 3 claws and install the spiral cable sub-assembly with steering sensor.
NOTICE:
When replacing the spiral cable sub-assembly with a new one, remove the lock pin before installing the steering wheel.
(e) Connect the connectors to the spiral cable sub-assembly with sensor.
NOTICE:
When handling the airbag connector, take care not to damage the airbag wire harness.
2. INSTALL UPPER STEERING COLUMN COVER
3. INSTALL LOWER STEERING COLUMN COVER
4. ADJUST SPIRAL CABLE
(a) Rotate the spiral cable sub-assembly with sensor counterclockwise slowly by hand until it feels firm.
NOTICE:
Do not turn the spiral cable sub-assembly with sensor by the airbag wire harness.
(b) Rotate the spiral cable sub-assembly with sensor clockwise approximately 2.5 turns to align the marks. NOTICE: Do not turn the spiral cable sub-assembly with sensor by the airbag wire harness. HINT: The spiral cable sub-assembly with sensor will rotate approximately 2.5 turns to both the left and right from the center. |

Low Power Supply Voltage Malfunction (C1241)
DESCRIPTION
If there is a problem with the skid control ECU (master cylinder solenoid) power
supply circuit, the skid control ECU outputs the DTC and prohibits operation under
the fail-safe function.
If the voltage supplied to terminal IG1 is not within the DTC detection threshold
due to mal ...
Vehicle Information Not Obtained (C1A02)
DESCRIPTION
When a new millimeter wave radar sensor assembly is installed, it receives vehicle
specification information (destination, steering wheel position, 2WD or 4WD, etc.)
from the main body ECU (multiplex network body ECU) and stores the information.
DTC C1A02 is stored when the millime ...
